I could not possibly overstate how important this book is. It's just a wee skinny volume, but inside are lovingly drawn illustrations of tools and their use. It's one of the few places where you can find nearly (or indeed completely) forgotten devices which made the modern world possible, and will once again pull us out of the post-oil time into a new world in the future. Sound over the top? Perhaps. Can you find everything here other places? Perhaps, but not in one place that I've ever seen. A certain type of person will treasure this book as much as a miser his gold. Count me amongst them.
